IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 193,9ll, dated August7, 1877 application filed May 26, 1877.

To all whom it may concern.-

Be it known that I, DAVID E. BANGS, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and valuable Improvementin Garbureter; and ILdo hereby declare that the following is a full;

clear, and exact description of the construc-v tion and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a vertical centralsection of my improved carbureter. Fig. 2 is a detached sectional viewof valve and fixtures. Fig. 3 is a plan view of the rose for thedischarge of naphtha; and Fig. 4 is a detail view of the float-rod,showing its attachment to the lever.

This invention has for its object the improvement of that class ofcarbureters for which Letters Patent of the United States were grantedto me, hearing date of October 31, 1876.

The object of the invention is, first, to devise means for replenishingthe carburetingtank Without the loss of gas or the admission of air;secondly, to provide means for determining the quantity of hydrocarbonoils in the carbureter; thirdly, to provide means whereby the deliveryof oils to the carbureter may be automatically attained; and,finally, toimprove the apparatus generally.

The nature of my invention will be fully described in the followingexplanation and set forth in the claims.

In the annexed drawings, the letter A designates the oil-reservoir, andB the carburetingchamber, separated therefrom by a division wall, a. Theformer is provided with a close annular condensingchamber, O, filledwith gravel, soap-stone, or other suitable material, and both thereservoir, and its casing, and the carburetingtank are surrounded by athird casing,'containing asbestus or other suitable non-conductingmaterials. This latter casing is lettered D in the drawings, and thefire-proof material D. The carbureting-chamber will be provided with alabyrinthine passage, through which the gas or air will pass on its wayfrom the induct-pipe to a reticulated opening leading into thecondensingchamber. This latter is provided with an educt leading intothe main, and the enriched gas, as in the patent aforesaid, is deprivedof 'its excess of carbon in the said condenser, so

that the deposit of the products of condensation in the mains andsupply-pipes is effectuopens above the said diaphragm into a-metal liepipe of larger bore, 11. This latter is provided with an aperture orapertures, c, and is surrounded by a reticulated cylinder, 0. When theupper end of the tube E is open the oil in reservoir A passes through itinto the carburetor below through the apertures c, all foreign mattersbeing excluded by the reticulated cylinder aforesaid.

Tube E is opened or closed as follows: Its upper end is made conical,and a leathershod plunger, E is passedinto the pipe I). This latter issuspended from or pivoted to the weight end of a vibrating lever, d,having its fulcrum in an upright post, d, and when free accuratelycloses the said tube E. The power end of this lever is bifurcated, andstraddles a metallic tube, E extending through the said diaphragm. Thistube is occupied by a rod, d carrying on its lower end, in thecarbureting-chamber, a float, F, and upon its upper end a cross-head, F.This latter projects at each end through longitudinal slots 0, formed intube E and its ends are connected with the forked end of the lever d bymeans of rods 6 When the carbureting-vat is adequately full the floatwill rise and lower the plunger E upon the conical end of pipe E,effectively closing it,

and cutting off the flow of oil from the reservoir into the carbureter.As the oil in the latter is carried off by vaporization the float willfall and the plunger be raised, thus reopening the communicating pipe E,and allowing the oil to flow from the reservoir to the carbureter. Therose 0 aforesaid is hemispherical in its general shape, and its upperplane surface is provided with oblique diverg- I ing discharge-openingsf through which the oil will be discharged scatteringly against theunder side of the diaphragm a. Such of the oil as is not vaporized whilethus sprinkled or divided falls upon spaced layers, G, of cloth,lamp-wick, or other similar material, dripping through which it will bevaporized as fast as may be required. These layers of cloth are aboutone-half inch apart, and are supported on a frame or other like device,in such a manner that the gas or air to be enriched passesuninterruptedly through it on its way to the reticulated opening leadinginto the condensing-chamber. As the naphtha passes outof the reservoirinto the earbureting-chamber a partial vacuum is created in the former,which in time would interrupt the flow of oil therefrom. This vacuum isfilled by a-fresh supply of oil as follows, without admitting air intothe reservoir or allowing gas to escape: The reservoir A is providedwith a two-way cook, .11, having two discharge-passages f f, and twoinduct'nozzles, g g These latter are connected, by means of bent pipesof any suitable material, with a second two-way cock, I, in afilling-vessel, J, two separate and independent nozzles, h h, beingprovided for the purpose. These are extended in distinct passages i t"into the said vessel, the former terminating just inside of the same.Passage i is provided inside of the vessel J with a pipe, K, extendingnearly to the top of said vessel J. When both the two-way cocks are openoil will flow, through passage '6, nozzle h, pipe 19, and itsconnecting-ducts in the lower cock, into the reservoir, filling up thevacuum in the same, while the vapors or air in the upper part of thereservoir will flow up the passage f, nozzle g, through passage h andpipe 1), into its connecting-passages in the upper cock, and will bedischarged into the upper part of the filling-vessel aforesaid. By thismeans an equilibrium is established between the reservoir and thefilling-vessel. To determine the quantity of oil in the reservoir A, Iemploy a metallic pipe, L, extending through the upper wall of the same.In this pipe is placed an end wise movable rod, 1, having on its lowerend a float, m, and upon its upper end a ball, at, having its seat in arecess at the upper extremity of the said pipe. If the oil be lowthefloat will fall and lower the ball proportionately; but if it .behigh, the float will rise and thrust therod out of the upper end of thepipe. When not in use the upper extremity of the tell-tale pipe will becovered with a screw-cap, 0. The oil having been fed in sufficientquantity to the reservoir, one or both of the cooks may be turned 0E.The pipes may be then disconnected, if it be deemed necessary, withoutloss of gas from the reservoir, or of oil from the filling-vessel. Inpractice, the lower two-way cock and the tell-tale are inclosed within achamber, N, when not in use, and the chamber being partly filled withwater the said devices will be effectually sealed.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. The combination, with a carburetingchamber and anoil-reservoir arranged above the same, of the connecting-pipe E, havingrose 1) upon its lower end and a valve-seat at its upper end, theexterior perforated guidepipe b, the reticulated guard 0, encirclingsaid pipe, the plunger E working in pipe I), the vibrating lever d, afloat, F, rod d connecting said lever and float, and a guide-tube, E, inwhich said rod reciprocates, substantially as specified.

2. The combination, with the feed-pipe E, having one end in thereservoir and the other in the carbureter, of the shield-pipe I), havingapertures o, the encircling reticulated guard 0,the rose 1), and theplunger E ,substautially' as specified.

3. The combination, with an oil-reservoir, a carbureting chamber,separated by a diaphragm therefrom, and a pipe extending through saiddiaphragm, of a rose applied upon the lower end of said pipe, andperforated on its .upper side, whereby the oil is dischargedscatteriugly against the said diaphragm, substantially as specified.

4. The combination, with an oil-reservoir, a carbureting-chamber belowit, a separatingdiaphragm, a pipe extending through the said diaphragm,and an inverted rose upon the lower end of said pipe, of an open-endedremovable frame, and the spaced independent horizontalevaporating-layers supported by said frame, substantially as specified.

5. The oil-reservoir A, having a two-way cock and separate induct andexit orifices g g and ff of the filling-tank J, having a twoway cock, I,with like orifices, the tube K, ex tending to the top of said tank, andthe connecting-pipes 10 p, substantially as specified.

In testimony that I claim the above Lhave hereunto subscribed my name inthe presence of two witnesses.

DAVID E. BANGS.
